Anyone riding a bicycle with a spring coil shock absorber on a hard and undulating surface will know how different and efficient the damping of pneumatic and hydraulic shock absorbers is.
Today\'s impact is a very advanced shock and damping vibration device that can work on compressed air power or liquid to dissipate the energy and vibration generated by the tire\'s contact with the road surface.
The impact pulse dissipated through the pneumatic and hydraulic cylinders with a sliding piston device.
The cylinder is filled with fluid or air as required.
Shock absorbers are used not only for engines and car suspension, but also for aircraft landing gear, drilling equipment, earth-moving equipment, oil rigs and many other large industrial machinery.
In rail transport, the principle behind the shock absorber is the same, which limits the steering of Bogota from one side to the other in fast-moving trains.
Pneumatic and hydraulic damping systems contain pneumatic cylinders or hydraulic cylinders that use steel pistons, piston rods, cylinder cylinders to help achieve damping effects.
When compressed air or fluid enters a pneumatic or hydraulic cylinder, it passes the piston up or down through the length of the cylinder.
The reflective action of the piston is either activated by compressed air or by the spring mechanism, and the spring returns to its original position.
These are also called single action cylinders.
There are many types of cylinders, which can be cylinders, electric cylinders, hydraulic cylinders or electric hydraulic cylinders.
Double acting cylinder (DAC)
Using the power of the air to move in two ways, one is to extend the itinerary and the other is to retract the itinerary.
The dual action cylinder has two ports, one for the outer stroke and one for the inner strokestroke.
As industry requirements may vary, there are a wide variety of holes and stroke configurations for pneumatic and hydraulic cylinders.
These may vary between less than inches until a few feet.
The power of compressed air or air may range from a few pounds per square inch to a few hundred pounds, generating enough power and a few thousand pounds of force.
The piston rod is usually made of tempered alloy.
The cylinder tube is seamlessly stretched, with precise sanding to achieve the smoothest finish to prevent corrosion and provide long life for the pistonseals.
The valves inside the pneumatic and cylinder help to adjust the flow of compressed air or fluid and maintain the pressure of the internal pressure of the pneumatic or hydraulic cylinder.
Some pneumatic cylinders have a diameter of 1000mm and are used instead of cylinders in special cases where leaking hydraulic oil can cause extreme danger.
Pneumatic and hydraulic cylinders are also suitable for automatic blinds of trains and electric doors, as well as automatic exits monitored and activated by sensors.
Low friction properties arranged in pneumatic and hydraulic cylinders enable it to be smooth and slow
Fast operation under low pressure, which is a safety consideration in the field of human transportation.
